This post will guide you through essential quadratic equation questions for the IPMAT entrance exam, providing several examples, solutions, and practice papers to help you master this topic.
Quadratic equations are a type of equation in algebra that can be rearranged in standard form as ax^{2}+bx+c=0 where x represents as unknown, and a, b, and c represent known numbers, and a ≠ 0.
If a = 0, the equation is linear, not quadratic, as there is no ax^2 term.
Examples of the standard form of a quadratic equation (ax² + bx + c = 0) include:
